Megjegyzések:The major limitation of native transcranial colour-coded duplex sonography (TCCS) in older stroke patients is the relatively frequent occurrence of an insufficient temporal window. Our goal was to investigate the relationship between the in vivo Doppler ultrasound image quality of the temporal bone, and computed tomography (CT)-determined thickness, density, and homogeneity of cadaver temporal bone. METHODS: Thirty-three moribund neurological patients who eventually died were examined by TCCS using the transtemporal approach. The sonographer categorized the quality of the TCCS image (excellent, intermediate, and poor). During autopsy, a rectangular sample of the temporal squama was removed, which corresponded to the area of the in vivo acoustic window. The thickness of the whole temporal bone, cortical, and cancellous (= diploe) bone as well as the density and homogeneity were determined by high-resolution CT. RESULTS: Thirty-seven temporal bones were obtained. The quality of the acoustic window was classified as excellent in 13, intermediate in 6 and poor in 18 cases. A significant correlation between the complete bone thickness, as well as between the absolute thickness of the diploe and the quality of the acoustic window was found: the thinner the bone/diploe, the better the colour Doppler signal. The thickness of the cortical plates and the homogeneity of the bones were identical in the three image quality categories. CONCLUSION: The transtemporal TCCS image quality depends mainly on the thickness of the cancellous component of the temporal bone.

Cím:A novel method of macropathologic and arteriographic examination of carotid specimens obtained from autopsy / Gernot Schulte-Altedorneburg, Dirk W. Droste, József Kollár, Csaba Hegedűs, Szabolcs Gomba, E. Bernd Ringelstein, László Csiba
Dátum:2000
Megjegyzések:Twenty carotid bifurcations were examined. During autopsy, carotid bifurcations were removed in toto. Unfixed carotids were ligated and cannulated for injection of an angiographic contrast medium followed by injection of a tissue-embedding medium at physiologic pressure and temperature. The carotid bifurcation was frozen and cut manually in 3-mm cross-sections. Photographs were then taken of every slice. Angiography, filling with tissue-embedding material, and sectioning were successful in all cases. In the macropathologic sections, the extent, configuration and location of atherosclerotic lesions could be identified.

Megjegyzések:BACKGROUND AND PURPOSE: The correct detection and quantification of carotidartery disease are of decisive impact on patient prognosis and adequatetreatment. In this study, we evaluated the ability of ultrasonography to detectand to grade carotid artery stenosis through a comparison of the in vivoultrasound findings with the planimetric analysis of the corresponding postmortemspecimens. METHODS: Shortly before their death, 59 critically ill neurologicalpatients (mean age, 70 years) were prospectively examined by extracranial andintracranial Doppler sonography and color-coded duplex ultrasound. Carotidstenosis was classified by hemodynamic and morphological ultrasound criteria.Carotid specimens were removed in toto during autopsy. Under standardizedconditions, specimens were redistended, sectioned, and histologically processed.Computerized planimetric measurements of the arteries were carried out andcompared with the ultrasound findings. Correlation of the ultrasound andpostmortem planimetric findings was available in 93 carotid bifurcations.RESULTS: Through both techniques, 46 carotid arteries were found to be normal.Steno-occlusive carotid lesions ranged from 8.5% to 100% lumen reduction.Overall, r=0.96 and adjusted R(2)=0.90. For the steno-occlusive carotid lesions,r=0.91. CONCLUSIONS: Extracranial and intracranial Doppler and color-coded duplexultrasound permits reliable detection and quantification of carotid arterystenoses and occlusions even under difficult examination conditions in criticallyill patients.

Cím:Measuring carotid artery stenosis-comparison of postmortem arteriograms with theplanimetric gold standard / Schulte-Altedorneburg Gernot, Droste Dirk W., Kollar Jozef, Beyna Torsten, Felszeghy Szabolcs, Modis Laszlo, Hegedus Csaba, Ringelstein E. Bernd, Csiba Laszlo

Megjegyzések:Five different calliper methods for assessing the degree of carotidartery stenosis and visual estimation ("eyeballing") of postmortem carotidarteriograms were compared with the planimetric gold standard of the areareduction at the site of the stenosis. METHODS: During autopsy 53 carotidspecimens were removed in toto from 31 neurological patients. Carotid arterieswere ligated and redistended to a physiological degree for standardisedthree-plane arteriography. Afterwards, the entire specimen was filled with anembedding medium under the same conditions and sectioned. Slices at the site ofstenoses were histologically processed. Computerised planimetric analysis of thelumen area reduction was performed and compared with the arteriographic findings.Arteriograms were evaluated by two independent observers by means of linearCommon Carotid Artery (CC), the European Carotid Surgery Trial (ECST) and theNorth American Symptomatic Carotid Endarterectomy Trial (NASCET), and squaredmeasurements (NASCET2, ECST2) after applying the pi r2 function. Further, threeindependent observers performed eyeballing of the degree of stenosis from thepostmortem arteriographies. RESULTS: Planimetry was carried out in 29 internalcarotid artery (ICA) and 17 common carotid artery (CCA) stenoses ranging from 8.5to 100%. The smallest mean differences of the degree of stenosis in % betweenplanimetry and arteriography were -0.5 and 0.6%. The narrowest 95 %-limits ofagreement covered a range of +/-24.1 and 26.3% of stenoses, and the highestcorrelation coefficients were both 0.9 for the CC and ECST2 techniques,respectively. By eyeballing, the degree of stenosis was underestimated by 13.5 to15.8% on average. The narrowest limits of agreement between two observers foreyeballing covered a range of 35%. CONCLUSION: Three-plane arteriography has onlya moderate accuracy and reproducibility in detecting and measuring carotid arterystenosis independent of the technique of measurement used.
